L-shaped overpass structure for T-shaped intersection

Abstract

The utility model discloses a kind of L-shaped overpass structures for T-shaped intersection, it is related to overpass technical field.The utility model includes a kind of overpass structure for T-shaped intersection, the plane of the overpass girder is oblique L-shaped, can be applicable to the T-shaped intersection of intersection angle 30~90 degrees, three directions of overpass are provided with ladder, ramp and straight ladder, the end of girder is provided with cantilever beam, and the straight ladder of three directions is arranged at cantilever beam place.The utility model solves the problem that three-way pedestrian crosses street in T-shaped intersection, the overpass can be applicable to the T-shaped intersection of different oblique angle, using conventional structure, easy to construction, beam height is smaller, complete function, high traffic efficiency, short detour distance, can satisfy the crossing demand of various pedestrians, such as general pedestrian, cart user, old person, disabled person etc..Meanwhile, solve the problem that the vertical fundamental frequency of footbridge does not satisfy and uses larger beam height, main beam and the leakage of joint of ladder, seismic beam safety protection is insufficient.
